`9 claims: (o. 7 -36):

This invention relates to' improvements in tiles,'- and has for its object the provision 01 a tile adapted to be used inv connection with a reen'- foreing framework for supporting concrete floors,` ce lings and the like.

It is particularly the object of this invention to provide, in connection with a reenforcing framework, a. reversible tile member which is supported from. the strengthening. framework either by means of soffit hooksand sofilts supported thereby, or by means of tile plates;

These and other advantages will appear from the following description taken in: connection with the drawings. s g

-This application is a substitute for my appli cation Serial No. 505,827, filed December 3 1, 1930.

Referring to the drawings: i

Figure 1 is a perspective View of the reentorcing framework showing applicant's tile structure and the means of supporting. it. l

Figure 2 is an end view of a reenforcing composite beam.

Figure 3 is a section through a reemorcing beam, the concrete structure embedding the 're enforcing beam, and the tile structure supported by the reenforcing beam. In this view there is shown, in connection with the soifit hook,- a tile plate. r p

Figure 4 is a View similar to Figure 3 but with 4 the tile plate removed and the tiles in a reverse Position! j ,a

Figure 5 is a View showing a section of the concrete structure with the reenforcing beams embedded therein, and a modified form ot tile. Figure 6 is a still further modified form of tile and, a modified form of supporting the` tile during the period of concrete pouring,

Figure 7 is a still further modified iormof s -pport for the concrete. v a Figure 8 is a longitudinal section through ad-- jacent ends ofthe bearing plate and the soifit,- showing the tongue on the bearing plate for supporting the endof the sofilt. 4 f l In Figure 1 there is shown in perspectivereen forcing beams and bars used in connection with The reference numerals l and 2 are used to designate two top bars arranged parallel one with' the other and slightly spaced apart. These two bars form the v upper members of a reenforcing' unit. The lower member ci this same' unit is formed. by two bars 3 and 4,. arranged. parallel to each other 'but spacedapart. c 4

' Connecting the top bars and the bottonr bars iea-plura1ity of diagonall y arranged web-berei;

These web bars are formed by properly bending asi'ngle'long bar.` The upper loops of this long bar` are welded to the' lower inner corner of the two upperor' top bars I and 2, as illustrated in Figre. (The lower l'oops of this bar are alternately welded to the bars 3 and 6. By this means the two top bars are spaced from each other about the thlckness of` the web bars 'I, while the lower two are-.spaced 'metrum, the other at a greater andmaybeheld apart by suitablemeans. i weldedbetweenlthe top bars adjacent one of thereof is a :hear plate 9'. To the lower end of this shear plate, which is diagonally disposed in relation to the reenforcing structure, are angle members '0, one on each side, to which is attached a bearing plate H. The edges of this bearing plate are turned up and have formed at one end tongues '2 by means of slots. The ends of the bars 3 and 4 are suitably supported by the' shearplutes- 9 and the bearing members H). Each bearing' plate has a tongue 8 formed therein to support one end of the soflit.

This framework here described is suitably Supor walls, and forms the strengthen'ing framework for the concrete floor or ceiling in whichit'is embedded. In order to form supporting means for, concrete there is provided, in connection with the reenrorcing'members, a sofiit "3 which is detachally supported by the reenforc-` ing units or. beams. somt is channel shaped andv has its` sides formed into rectangular seats M; as'shzow'' in Figure 1, When the sofiit is in po'sitioi'o 'use the channel part of the soffit extends downwardly so thatthe rectangular seats M extend upwardly.

`'The smts are supported on the Strengthening beams'br means of sofit plates or brackets '5. Each bracket' has` extending upwardly therefrom a pair'oi hooks '6, 'Each hook is adapted to engageone of lower bars 3- or 4. Extending downw'ardlr from. the soifit bracket are two lower hooks H whichextend through suitable openings in th'e soflit for: the purpose of supporting the soffit' beneath the'reenfiorcing beams or units. These hooks may be'bent or twisted beneath the sofiit cr' the soffit be supported by the hooks by means of rode or p'lns inse'ted in the hooks beneaththe somt. n

After the reenforcing members have been constructedtwo adjscent ones' are tiedtogether by meansof temperature expansion rods '8, as shown in 'Figure 1; When the reenforcing beams have* beenreonstructed. and placed. in position on the' members, and properly spaced with a saint beneath each reenforcing unit,

steel forms I 9 may be supported in the rectangular seats M. There may be also supported above the sofits ceiling tiles or members 20. Each plate has longitudinal grooves 2' therein on each side. At each edge of the ceiling plate are lateral grooves 22 which form along the edge a tongue 23 in line with one of the faces of the tile, and a tongue 24 which is out of alignment with the other face of the tile.

The sides of the ceiling plates are supported on the sofiit members by means of plates 25. These l plates are of any suitable material and have turned-up edges 26, and intermediate the turnedup edges are doVe-tailed tongues 2" about which the concrete is to fit for supportingtheplates after the concrete has beenpouredand the fioor" or ceiling structure has been made. The con-,

crete floor or ceiling structure is indicated by the numeral 28. In Figures 3 and 4 there are shown two positions of the ceiling plate 20. In Figure 3 the plates are supported on the plate 25. As shown in this figure, the plate 25 is supported by the sofiit, which is supported'by the soffit hooks.

When the concrete, has been poured and the framework removed the plastering maybe done over the lower surfaces of the ceiling tiles or members20 and the plate 25., In this position the tongue 24 rests upon the plate 25. Thistongue is sufliciently short that the plate 25 may engage thetongue. and still maintain its lower surface in line with the lower surface of the ceiling plates so that plastering may be done without any ridge or irregularities appearing.

When the plate 25 is not to be used in connection with the ceiling plates the ceiling plates are arranged as shown in Figure 4; In this figure the short tongues 24 are on the upper side of the plate, whereas the long tongues 23 are on the lower side. In this form, when the soffit is removed the lower hooks may be bent up or broken and the lower surface plastered over, the same as would be in case of the structure shown in Figure 3. V

In Figure 5 there is shown a slightly modified form of ceiling tile or member 29. In this form along one edge there is formed a hook member 30 and an adjacent groove 3'. Along the other side of the tile is an extension 32, which has a dove-tailed tongue 33, and along the end is a hook member 34 adapted to be engagedby the hook member 38 and the slot 3'. This structure is shown in Figure 5. In this form the extended part of the tile is supported by the soffit, while the other side of the tile is supported by the hook 34 on the adjacent tile. In this form, after the concrete has been poured and settled, the soffit may be removed by breaking the .hooks and removing therefrom pins 35 which cooperate with the hooks in holding the ceiling tile in place.

In Figure 6 there is shown a slightly modified form of concrete structure with a modified form of tile. In the form shown in this figure there is supported in each seat '4 a bracket 36. This bracket supports tiles 3" around which the concrete is poured. After the concrete has been poured and the structure hassuificiently set the soffits may be removed and with them the brackets 36, after which the proper plastering may be done.

In the form shown in Figure 7, instead of having the brackets 36, a filler plate 38 is supported in the seats '4 and upon these plates and around the reenfo'r'cing beams is ?poured the concrete which forms the floor ,or overhead structure. Af-

" ter the concrete hasproperly set the sofiits may be removed and the filler plate 38 removed. In this form the filler plate has downwardly extending projections 39 that fit into the seats M.
